I also needed to add a mflag.IsSet() function that allows you to check to see if a certain flag was actually specified on the cmd line. Per #9221 - also tweaked the docs to fix a typo.

Package mflag (aka multiple-flag) implements command-line flag parsing.
It's an hacky fork of the official golang package
It adds:
-
both short and long flag version
./example -s red./example --string blue -
multiple names for the same option
$>./example -h
Usage of example:
-s, --string="": a simple string
It is very flexible on purpose, so you can do things like:
$>./example -h
Usage of example:
-s, -string, --string="": a simple string
Or:
$>./example -h
Usage of example:
-oldflag, --newflag="": a simple string
You can also hide some flags from the usage, so if we want only --newflag:
$>./example -h
Usage of example:
--newflag="": a simple string
$>./example -oldflag str
str
